我正在尝试使用以下命令在python 2.7中安装模块mysqldb：
pip install mysql-python
错误：

我正在使用Linux RedHat，操作系统版本：
Linux 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38 EST 2015 x86_64 x86_64 x86_64 GNU/Linux
我安装了以下软件包：
$ yum install gcc
$ yum install python-devel
$ yum install mysql-devel
我错了什么？
提前致谢
答案 0 :(得分：0)
鉴于您在RedHat，您可以使用以下命令安装此模块：
yum install MySQL-python
刚在docker实例上测试过：
[root@c72015444834 /]# yum install MySQL-python

要检查它是否已实际安装：
[root@c72015444834 /]# python
Python 2.7.5 (default, Jun 17 2014, 18:11:42)
[GCC 4.8.2 20140120 (Red Hat 4.8.2-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
但是，我的建议是你跳过mysqldb，因为你遇到的问题远比我的经验所希望的要多。 Intead跳转到Connector / Python，这是一个标准驱动程序，可以在没有pip问题的情况下安装，并且具有与mysqldb相同的接口。
安装它：
pip install mysql-connector
用法与mysqldb相同，因此切换应该很简单：
import mysql.connector
db = mysql.connector.connect(host=MYSQL_SERVER, user=MYSQL_USER, password=MYSQL_PASS, db=MYSQL_DB)
cursor = db.cursor()
try:
strSQL = '''select field1, field2, field3 from yourTable where field4 = %s and field5 = %s'''
cursor.execute(strSQL, ("asdf", "qwerty"))
for row in cursor:
field1, field2, field3 = row
# do your stuff
finally:
cursor.close()
db.close()
